| Description: | Data from the Advanced Very High Resolution Radiometer (AVHRR) were used in a cooperative project, sponsored by the U.S. Department of Agriculture, Forest Service, Southern Forest Experiment Station, and the United Nations, Food and Agriculture Organization (FAO), to map Mexicos forest cover types.To provide satisfactory AVHRR data sets for the project, the sensor scan angle needed to be calculated for data points in the composite image data, and the clouds had to be removed and composite image data created from individual data sets. Techniques used to accomplish those two tasks are described here. Concepts illustrated here should be applicable to other similar projects. |
